contained in this submission.

Suggested action

The submitters consider compact RDF representation and exchange highly relevant for the future of RDF. Although probably out of the scope of the current RDF working group [RDF Charter], we suggest that the Consortium considers the present submission as an input for work in a new Efficient RDF Interchange working group at W3C, analogously to similar W3C efforts in the XML realm, such as the EXI Working Group [EXI].

Resources

To help with this work, each submitting organization expects,
but does not explicitly commit to this,
to be able to provide members of the working group. DERI Galway at the
National University of Ireland, Galway, Ireland further expects to be
able to provide editors for the deliverables of the working group. The non-member co-authors of this submission would be available to join a respective working group as invited experts, if considered appropriate by W3C.
